Specification o 'lamination med January MAYO VEN- ABLE, a citizen of the United States, residing at Pittsburgh, in the county of Alle` ghenyiand State of Pennsylvania, have in 'vented certain new and nuseful Improve# ments in Beam-Molds, of ywhich the following is a-specifieation.-

Ther'invention relates to the 'forms or molds employed for casting concrete beams. It has for its primary objects; the provision of a mold or form which may be readil7 and conveniently' assembled and disassembled, and' which 'may be einplovedv for casting beams of dill'elent dimensions; the provision oi ali-moldfor forinwvherein the sides of the inold inay'be removed for reuse Without re moving thev bottoni of the mold; and in general the provision of an improved and simplified form of mold which can be more easily handled .than the molds heretofore employed, and at less expense. Certain einbodinentsI of the invention are .illustrated in the accom"panyingi,` (.lrawings, wherein:-

Figure l is a perspective view showing the. gene al arrangement of the parts of the mold when in position for use; 2 is an end View of the mold of'Fig. l; Fig. is a transverse section onthe hne lll-lll oi Fig. 2; Fig'. Zl is an end elevation showing amodiliedconstruction; and Fig. 5 is an.

The bottom plate f3 is preferablva wood plank, but some male rial other than wood might be used il dcsired.

larly' as 'te Width, as the distance between the side plates l and 2 may be varied by using planksA of varying Width. The planii secured between 'the side edges of sneh plank and the side plates l and 2 by pulling such side plates toward each other, so that they tightly engage and grip the edges of the plank. l 1

The ine-ans whereby the side plates l and 2 are clamped against the side edges of the plank f5, and whereby the side plates l and 2 are held in parallelism are shown in Figs. 2 and 3. llrorn these views it Will 'be seen that the flanges of the stiileners ilmll below the side plates l and il, are slotted, and the these slots receive the elaniliing bare 'l 8, the bar 7 being riveted or otherwise rigidly secured ir; left hand end to the ange et the stiflener .6', and extending slidably .at its other: end through the slot bar 8 is riveted lat' its right hand end to the flange oi the stii''ener il, and pa: slids ably through the slot in the flange ot the `stifl'ener 6 at. its other end.. The liars l and 8 are provided 'with a plnralitj,7 oi liorizontal slots 9 arranged in staggered relation, so that if one slot does not come in the proper position with respect to the slot SYL in the'ilange of stiiiener, the ,slot in the next rovv will come in sneh posiu tion with respect to the slot 9, andv the parte are securely looked in position by means of in position. l into their proper slots serves to draw the side plates l and 2 toward each other gripping' the side edges of the plank 3, the deH ,aree of pressure upon such side edges being regulated by the distance which the wedges aredriven through the slots. lt will against the side edges ot' the bottoni plate. and so hold such plate seei'lrely in position, but 'the securing bars serve to hold the sidf 'plates l and 2 in substantial parallelism. The har 8 being riveted to the sti'lleoer C 1its-lefthand en(A against vertical more.

The side plates 1 and 2 are thus held rigidly in substantial u parallelism with their planes at right angles With thebars 7 and 8. The series of endto-end slots 9 permit an adjustment of the side plates toward and from each other to make beams of different thickness, While the clamping action of these -plates upon the edges of the plank 35per1nits it to 'be placed atany desired vertical position, thus giving beams of diiferent depth, the shores 13 which assist in supporting the plank being lengthened or shortened as required, by blocking up from beneath.

The side plates 1 and 2 may be'supported from beneath by meansof transverse mem! bers 11 and supporting yshores 12 as indicated in Fig. 1, or may be su ported from the iioor beams as illustrated 1n Fig. 5 and hereinafter described. YThe bottom plate 3 is preferably supported from other shores 13.' The support for the side plates and that for the bottom plate are thusmadeindependent', and as a result one portion of.-

the apparatus '.nay be taken down Without the necessity of taking down the other portion. In practice the concrete beams require the support of the bottom plates for a comparatively long period, While the side plates 1 and 2 vmay be removed with safety only a short period after the concrete has set. These side plates 1 and 2 may therefore be reused while the bottom plate 3 'is still in position. inasmuch as the side plates can.

be reused rapidly, the quantity of side plates required for any given piece of work is reduced to a minimum, the only parts re-` quired in large quantities being the supporting planks 3, which are relatively very much cheaper than the metal portions of the apf paratus. The independent supporting .of the side plates and bottom plates thus becomes an. important factor in reducing the cost of equipment. ln those cases in which it is not necessary or desirable that the side -plates be taken down before lthe bottom plat/catho bottom plates may be supported from the side plates in any approved ninnner, and the independent shores'r13 dispcnse'clvvith. l'

A modified constructionv is illustrated in Fig. 4. In this construction the free angle member 14 takes the plaee'of .the flange 4 in the construction of Fig. 1', andv the' addi- 'tional rmgles 15 and 1li-are employed,suh

angles being riveted to the'side plates. The angles 15 serve to-support the floor beams 17, and the angles 16 serve to give additional stiii'ness to the lower edges of th'el side plates 1.and 2. The plank 3y and the clamping bars 7 and 8 correspond to the parts 3. 7 and 3 in the apparatus shown in Figs. 1, 2 and 3. The side plates are sup' ported from beneath by the shores 12 carrying the erossmembers 11, and these,v side plates in turn support the iloor-beanisd.

The corrugated sheet lnetalform member 18 overlapping' the.angle 14 may be employed to receive the concrete forming the floor above the beam. By making the angle .from that'of Figs. v'1,152 and' 3 primarily in that t-he side plates Pand 23 are supported from the floorv beaihs`21 instead of being supported by means; of the blocks .11 and,

The ends of the sti eners 63 are welded to the angles 25 which fit intorabbets cut in the ends of the 'beams 21, such stiifeners being riveted tothe side plates 1 and 23. angles 25 are secured to angles 26 in order to provide a bearing upon the ends of .the beams 21.. The space between the an les 26 and the flooring 24 is bridged either yr extensions of the plates'23 or by means of the lap plates 27. The bottom plank 33 is supported from beneath bymea'ns of the shores 138, and the lower ends of the side plates.-
